The work done by the net force on the block of mass 0.8 kg is 19.6 J.

What is work done?

Work is said to be done whenever a force moves an object through a distance.

To calculate the work done by the net force on the block, we use the formula below.

Formula:

  • W = mv²/2....................... Equation 1

Where:

  • W = Work done by the net force on the block
  • m = Mass of the block
  • v = Speed of the block

From the question,

Given:

  • m = 0.8 kg
  • v = 7 m/s

Substitute these values into equation 1

  • W = 0.8×7²/2
  • W = 19.6 J

Hence, the work done is 19.6 J.
